Awesome thanks for the info mother focus. What I am doing will help with strengthen the stock crank and will be a lot cheaper than a bullet crank. I will be doing testing this summer to make sure it does work before releasing info out

Your money so you will do what you think is best , heat treating a cast Iron crankshaft only buts a surface hardening on and and wont make you crank any stronger or last any longer , its the flex in the crank that brakes them and the only way to remove most of the flex is going to a stronger metal like steel cast or from billet , this doesnt mean they still dont bend and flex they just do it less and can take more to a point , they can still brake

With building dozens of race engine a year for over 20 years I have tried heat treating , nitrided , cryo etc etc , they dont work but thats your call to find out just trying to pass on information from something I have had customers try many times and it failed

Tom

Nitrid won't work on these cranks anyways. Thanks for the info but yes I will still try tho.

thanks for the correction tom. and i thought that cryo freezing the crank worked pretty good. i KNOW i remember you talking pretty hard about that several years ago. that must have been right after you started doing it and before you realized it wasnt as good as you thought maybe? what kind of torque were you putting down?
